[PROBLEMS] To increase the yield of rice bran oil in the recovery of fats and oils from rice bran and to increase the content of bioactive sterols and oryzanol. SOLUTION: When extracting oil from rice bran, rice bran is previously treated with an enzyme, whereby the fat and oil yield is 20% by weight or more based on rice bran and the sterol and oryzanol content is 1.8% by weight or more. A method for increasing the yield of bioactive rice bran oil. As the enzyme, an enzyme mixture containing amylase, cellulase and protease is desirable. |
